19 Now therefore you are no more strangers and foreigners; but you are fellow citizens with the saints, and the domestics of God,
20 Built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone:21 In whom all the building, being framed together, groweth up into an holy temple in the Lord.
22 In whom you also are built together into an habitation of God in the Spirit.

Psalm: Psalms 117:1-2

1 O praise the Lord, all ye nations: praise him, all ye people.
2 For his mercy is confirmed upon us: and the truth of the Lord remaineth for ever.

Gospel: John 20:24-29

24 Now Thomas, one of the twelve, who is called Didymus, was not with them when Jesus came.
25 The other disciples therefore said to him: We have seen the
Lord. But he said to them: Except I shall see in his hands the print of
the nails, and put my finger into the place of the nails, and put my
hand into his side, I will not believe.26 And after eight days again his disciples were within, and
Thomas with them. Jesus cometh, the doors being shut, and stood in the
midst, and said: Peace be to you.
27 Then he saith to Thomas: Put in thy finger hither, and see
my hands; and bring hither thy hand, and put it into my side; and be
not faithless, but believing.
28 Thomas answered, and said to him: My Lord, and my God.
29 Jesus saith to him: Because thou hast seen me, Thomas, thou
hast believed: blessed are they that have not seen, and have believed.
